A British militant, fighting with Islamic State in Iraq, has claimed he would be 'honoured' to murder a western captive.
He also says he is prepared to return to the UK to spread terror here.
ITV News Political Correspondent Romilly Weeks reports:
Investor confidence "has been hurt" by terrorist attacks carried out in emerging economies rich in natural resources, an expert has warned.
Jordan Perry, a principal political risk analyst at Maplecroft, said:
Libya, Kenya and Egypt are among a handful of countries to witness a significant increase in risk...and investor confidence in key sectors, including tourism and oil and gas, has been hurt.
When faced with rising security costs and decreasing safety for their personnel, companies can, and do, reconsider their country-level commitments.
China, Egypt, Kenya and Libya are most likely to experience significant increases in terrorist attacks, according to risk experts.
Maplecroft's Terrorism and Security Dashboard found:
- Twelve countries are classed as "extreme risk"; Iraq topped the list, followed by Afghanistan, Pakistan, Somalia, Yemen, Syria, Lebanon and Libya.
- It also includes the growth economies of Nigeria, the Philippines, Colombia and Kenya.
- Iraq, rated as the highest risk country, recorded more than three times as many acts of terrorism as Pakistan with 3,158 attacks resulting in 5,929 deaths - an increase of 2,188 on the previous year.
- In Nigeria, the campaign of violence by Islamic militant group Boko Haram saw the country record the highest number of fatalities per attack, resulting in 3,477 killed - an average of 24 people killed per attack, compared to two deaths per attack in Iraq.
The number of civilians killed in a terrorist attack has risen by nearly a third in a year, British experts have found.
Risk analysis company Maplecroft found deaths across the globe from acts of terrorism rose 30% compared to the previous five-year average.
Maplecroft found in the 12 months before July 1 there were 18,668 fatalities compared to an average of 14,443 for the five years before that - a 29.3% increase.
According to a Maplecroft dashboard, Iraq has endured the highest number of attacks in the last year with 3,158 incidents, while terrorism in Nigeria is the world's deadliest, recording the highest number of deaths per attack, with an average of 24.
Babar Ahmad, a British cyber-jihadist, has been sentenced by a US court to 12-and-a-half years' imprisonment for helping support terrorism through the internet.
Ahmad, 40, had admitted conspiracy and providing material to support the Taliban.
The Londoner has already spent almost 10 years in prison in the UK and US and had been hailed as an 'exemplary prisoner' by British prison officials.
Delivering sentence at the court in New Haven, Connecticut, Judge Hall said Ahmad helped allow Osama bin Laden to be protected when he was plotting the September 11 attacks by supporting the Taliban.
She stressed that he had no knowledge of the plot however, and there was no evidence he supported bin Laden's al Qaida terrorist group.
Ahmad is expected to carry out the remainder of his sentence in New York's Metropolitan Correctional Center.
Muslim leaders in Britain have condemned the extremist group Isis and say it does not represent the majority of Muslims.
Representatives from both the Sunni and Shia groups in the UK expressed their 'grave concern' as British Muslims continue to travel to the Middle East to join the ongoing violence.
Maulana Shahid Raza, of Leicester Central Mosque told Sky News: "Isis does not represent the main Sunni Muslims' ideology."
Shuja Shafi, of the Muslim Council of Great Britain, said: "Violence has no place in religion, violence has no religion."
The Conservative MP Mark Pritchard has said that new laws should be brought in requiring the families of people who travel abroad to take part in jihad to contact police.
"I think we need to look at every measure that would increase our national security", he told Good Morning Britain.
He added that it was "incumbent" on family members to report those who had gone abroad to fight in the interest of protecting their own local communities and the national interest.
Many young people who travel to fight with militants in Syria and Iraq are recruited by extremist leaders taking advantage of their personal crises, a spokesman for an anti-extremist group has said.
Haras Rafiq. of the Quilliam Foundation, said that mosques teaching an extremist jihadi form of theology need to consider what it means to be both British and a Muslim.
A British engineering student who has appeared in a recruitment video for the terror group Isis has said that he wants to die fighting.
Abdul Raqib Amin, who was raised in Aberdeen, said that leaving Britain was one of the happiest moments of his life because "as a Muslim you cannot live in the country of Kuffars (disbelievers)."
He said he was ready to go anywhere to fight, adding: "I want to die for the sake of Allah".
An British engineering student who travelled to join Isis militants in Syria has said that he is ready to fight to the death.
Abdul Raqib Amin, believed to be in his 20s, admitted to missing his parents in an interview with Good Morning Britain, but said that there was no turning back.
I'm going to stay and fight until the Khilafah (rule of Islam) is established or I die.
Raqib has been identified as one of the British militants in a recruitment video for Isis, alongside fellow British jihadists Nasser Muthana and Reyaad Khan. In it, he said that he had suffered from depression while living in the West, before adding: "The cure for the depression is jihad.”
But a former schoolfriend has said that he believed that Raqib had been "brainwashed" by Islamic extremists.
